Case Trimming Before or After Resizing?

[sstephenson]

Today I started reloading my first rifle cartridges (.30-30 Winchester). After having decapped, re-sized and then trimming my cases, it occured to me that maybe I should trim before re-sizing. What's the proper order? Thanks.

You need to trim after resizing, always. After you resize it stretches the case neck and needs to be trimmed.

Makes sense. Thanks morrow.

ALWAYS after re-size, the case length does not increase until it is sized.

Yup, after resizing as the brass grows when you resize it.
